摘　　要：文中主要研究北京新机场线辅助逆变器的错时启动和减载控制。通过列车网络控制及诊断系统(Train Control and Monitoring System,TCMS)的逻辑控制,实现并网供电方案中辅助逆变器的错时启动,保证所有辅助逆变器向整列车的供电母线输出同相位的中压380 V,避免多台辅助逆变器同时启动,造成辅助逆变器的同步失败。TCMS根据辅助逆变器故障数量,通过减载控制来调整负载的情况,保证整车设备的工作需求,并避免中压负载超负荷对辅助逆变器造成不良影响。This paper mainly studies the asynchronous start-up and load shedding control of auxiliary inverter in Beijing New Airport Line Project.The Train Control and Monitoring System(TCMS) uses logical control to realize the asynchronous start-up of auxiliary inverters in grid-connected power supply scheme,which guarantees that auxiliary inverters output the same phase of 380 V to the medium-voltage bus of the train.It avoids the synchronization failure of auxiliary converters when multiple auxiliary converters start simultaneously.According to the number of faults in the auxiliary inverter,TCMS adjusts the load by load shedding to ensure the working demand of the vehicle equipment and avoid the negative impact of medium voltage load overload on auxiliary inverters.
